Double open ended screw cap

ABSTRACT

When one has liquid in a screw top container this open ended screw cap can make salvaging the contents simple, and save time. By locking one container vertically over the other and allowing gravity to do the work. Twin containers may be used with a single size screw cap, or varying size containers may be joined by the use of screw caps with different sized ends. These caps could be manufactured in any material that is in use today to manufacture single closed end screw caps.

BACKGROUND OF THE INVENTION

Liquid handling, when someone is left with a small amount of heavy liquid in a screw top container and wants to salvage it for economic or recycling purposes, this may take more time than one is willing to lend. A simple, inexpensive and time saving way to accomplish this is what I am presenting.

SUMMARY OF THE INVENTION

A system for moving salvageable liquids in twist top containers by using a double open ended screw cap that locks the containers in a vertical position; thereby accomplishing the desired results. Gravity does the work over time. The utter simplicity and low cost of manufacture makes my device attractive for the use intended.

DETAILED DESCRIPTION OF THE INVENTION

A system for salvaging liquid in twist top containers using gravity. The flow of liquid is controlled in response to up ending one container over the other with this invention locking the containers into the desired position. Double open ended screw caps are of injection molded plastic or any other suitable materials, and are made in any and all sizes of screw caps in use and any combination of sizes joined together. This allows containers with different size screw tops to be joined together.
